Myself like everyone else who has a lowered xb with above factory wheels and tires, I am worried about my rear toe being out. I have search and have yet to come up with a fix for the issue on different forums. I have found that ingalls makes a shim kit that is suppose to fix the camber/toe and it comes in different degrees. I am waiting on them to return my email to see if their shims will indeed correct the rear toe or just the camber. Both of my rears are out almost a 1/2 degree from 0. I am running TRD Springs on 19x7.5 Racing Hart Cr's wrapped around 245/35 Goodyear GT's. The ride is great and it doesnt pull in the least. I know that it is aligned to the specs of a stock xb with stock wheels and tires. I asked the dealership that checked the toe if toyota has release a alignment spec for a TRD Spec Xb, basically asking if there was a different spec for one with the TRD Springs and TRD wheels and 235/35's. They said that Toyota has only released one spec. So unless Ingalls has the fix it looks like I will be rotating the tires every month!

 

So when was the last time you had an alignment? And what were the settings? Is it within spec now?

 

Just received the email from Ingalls. Looks like they have the fix to correct the toe. I am going to order a set and I will let ya'll know how it goes. looks to be a simple install. Ingalls email is below.

The shims have a thick side and a thin side.

They come with a chart that shows the correct installation clocking position to achieve the camber and/or toe adjustment needed.

31501 is a 1/4 degree shim
31502 is a 1/2 degree shim
31503 is a 3/4 degree shim
31504 is a 1 degree shim.

If both of your rear wheels are 1/2 degree toe out the (31502) shims would be installed with the thickest point side towards the rear. This moves the front of the tire inwards.

 

I had an alignment two days after I bought it which was now 4 weeks ago with the stock wheels and tires when the TRD Springs were installed. I had Goodyear where i bought the tires from recheck it monday and they said that they could not correct the toe problem. I just let my toyota dealership about an hour ago and they said that they cannot fix the rear toe. the shim looks like a "Correct Fix".

 

How is the toe going to hurt the car exactly? According to Toyota, even the 18" wheels and perelli tires are set to the exact alignment specs as the stock wheels are with trd lowering springs and trd shocks. Why would they not provide specs that better suit their trd setup? Weird.

 

Toe won't hurt the car, but it will certainly wear some tires out quickly.

 

exactly. the problem is that the tires are pointing either in or out and not straight. this will cause the tires to cup (unever wear) or wear one of the sides out really fast. there is no way for the factory to correct the toe because there is no adjustments that can be made, aftermarket parts must be used. The factory can correct camber. Probably why the 18" wheels are able to be aligned is that the tire is closer to the overall size of the stock tires compared to 19" or 20" tires. I guess the TRD setup works with the stock specs but what the dealership told me was that toyota sets them up from the factory and they cant fix the rear. The shims are the only fix for the toe.

 

Nothing weird about it. The correct toe isn't a function of springs or bars or rims or tires or whatever, it's entirely a function of vehicle geometry. Toyota/Scion have already made the optimal specs available -- they don't change. Meet the specs for least tire wear.

 

But the rear is not attainable under some instances.

 

That doesn't change what the optimal alignment specs are for the car. If you make mods and are no longer in spec, that doesn't mean there's some other alternative spec that's correct, it just means your mods result in your vehicle alignment being out of spec, and you can expect sub-optimal tire life.

 

there is a setting for stock. the question is should there be a different spec when your ride is 2" lower than stock and your tires are 2" taller. this could be why some people are noticing their xb pulling after alignment to factory specs and tires wearing out. The question would be is the spec related to the vehicle or to the suspension set up.

 

People on here are scrubbing front tires from NOT doing an alignment after lowering, not from aligning.

Also, where do you come across discussion on tires that are 2" taller. I've yet to read of an installed rim/tire combination that resulted in a significantly greater diameter than factory. If they did, they would throw off the speedometer and odometer big time.

 

2" wont throw it off big time. I'm at 1" over stock and anybody who is running 20" with some rubber (35 series) will be 2" over. I'm at factory specs now besides the rear toe and I'm setting that up to factory specs.

 

just bc you didnt read about it doesnt mean its not out there. i put some 243/35/20's on an xb 2 weeks ago. he has the same issue i have with rear toe. I'm gonna do mine with the shims and if it works i'm gonna have a few customers come in and do the same.

 

You're not talking about the tire, you're talking about the rim, and whatever combination of tire and rim you use to get your diameter, it's not going to change the optimal toe.

Also, if you have excessive camber on your tires (front or back) respective tire wear will be accelerated. Different alignment flaws result in different wear patterns. Wrong toe scrubs inside or outside tread edges whereas wrong camber creates uneven side to side tread wear. Correct specs are the factory specified specs, lowered or not.

Good luck !

 

Did you get the shims? Did they work? Everything on my car was good after alignment except rear toe.

 

The spec doesn't care about lowering. Wear is wear and if you are dropped and your alignment specs are out you can expect accelerated wear. This is something one would be expected to understand before installing the lowering suspension. Ingels makes camber bolts for the front suspension that can correct that problem, but I've yet to learn of a solution for the rears. My rears are spec marginal, but I'm OK with that, I looked into it in advance and knew what I was getting into.

 

I'll ask again and add to my post....

I found the ingalls shims (http://www.ingallseng.com/31501-Seri...tact-Shim.html) and they are only like $9 so may be worth it just to try. I got my alignment at tire kingdom because they were the only ones around that could do it or at least just this one TK here cuz they have a sunk in machine and my car with drop and bodykit was way to low for anyone else, no one would touch it. I got a year unlimited alignment so if I get them it won't cost anything to do the alignment. Maybe I'll just ask them if no one has tried. I'm just tired of going through tires. Went through stock set and two aftermarket tires already and only have 20K miles. Not to mention mpg have dropped like crazy.

 

About to put on brand new tires/wheels myself, I'll be getting an alignment and then ordering the necessary set of these..

 

Anyone tried them out yet? I just did my alignment and right rear is 0.41 toe and suposed to be 0.20 max. Left is at 0.19 so its barely within spec.
